Whenever by order of the commission any street or alley, or any portion thereof, has been temporarily closed for constructing improvements thereon or repairing the same, it shall be unlawful for any person other than the city contractor or the city's employees, in case the city itself is constructing such improvement, to operate any vehicle thereon, or to interfere with, take down or remove any of the lights, barricades, guards or barriers, or any portion thereof, surrounding said closed portion of such street or alley. The chief of police or city manager may order the temporary closure of public ways when public safety requires. The city manager may order the temporary closure of rights of way used for an outdoor event after considering safety, traffic disruption, availability of alternate traffic routes, and other impacts of closure. Temporary closures by the chief of police or city manager shall be reported to the commission at its next meeting. (Ord. 2898, 8-28-2000)
